Photoshop: Unable to save an animated gif with a loop count > 32

I can set the loop count to be a number greater than 32 from within the timeline panel, but when I get to the Save for Web screen, it changes the looping options to Other(32). If I try to manually change it to > 32 on the Save for Web screen it tells me a value between 1 and 32 is required.

Why is this limitation here? If I use a tool like Gifsicle I'm able to create > 32 loops.
